N Channel Mosfet High Side Switch Circuit

This is a simple circuit where a n channel enhancement mode mosfet will turn on or off a light.
N channel mosfet high side switch circuit. Assume the device is initially off. In the low side configuration the load is connected between the drain and v while the source. This transistor connects between v and the load. The n channel high side switch.
Then the p channel mosfet is used to switch the positive supply to the motor for forward direction high side switching while the n channel mosfet is used to switch the negative supply to the motor for reverse direction low side switching. To switch v with a n channel mosfet use a n channel mosfet with drain connected to v and the load connected to source. In order to operate a mosfet as a switch it must be operated in cut off and linear or triode region. There are a variety of configurations for driving the two mosfets with many different applications.
Used as a high side switch a p channel mosfet in a totem pole arrangement with an n channel mosfet will simulate a high current high power cmos complementary mos arrangement. Based on the circuit it looks like it is a typo where the arrow is pointing the wrong way for a p channel mosfet. There s a catch with this arrangement though the mosfet switches on based on the vgs threshold being reached and the source voltage in this arrangement changes between off 0v and on vin. 2 n channel mosfet configured as high side switch you can quite easily see the difference between the high side configuration and the low side configuration.
Although the p channel mosfet cannot complement the n channel in both on resistance and capacitance simultaneously such combinations as the low threshold p channel tp0610 and the n channel 2n7000. The opposite of the low side switch is the high side switch. For that matter the first circuit drawings that describe the negative vgs using only a positive supply for a p channel mosfet are drawn using n channel mosfets. In order to do this the gate voltage must be magnified in some way.
